Patternmaking for underwear combines technical engineering with design, requiring precise calculations for stretch and negative ease to achieve a second-skin fit [1.1, 1.2, 1.3]. Key elements include strategic seam placement, complex 3D cup shaping for support, and integrating hardware, often utilizing CAD software to simulate fabric tension before physical prototyping [1.2, 1.3].

Key Components of a High-Quality Underwear Patternmaking PDF:

  1. Block/Sloper Creation: Instructions for drafting a basic panty block and bra cup block based on personal measurements.
  2. Grade Rules: How to scale between sizes (grading) for mass production or home sewing.
  3. Stretch Factor Calculations: Unlike wovens, underwear uses elastane, spandex, and power mesh. A good PDF explains negative ease.
  4. Style Transformations: How to turn a basic brief into a thong, a high-waist, or a boyshort.
  5. Lingerie-Specific Seams: French seams, elastic application, and lace joinery.

She pulled out a brittle, yellowed mannequin torso. Then a rusted rotary cutter. And finally, a cracked, coffee-stained laptop that wheezed to life when she plugged it in.

Here are some tips for creating a flattering underwear design:

Step 3: Cutting your Muslin Do not use woven calico for underwear muslins. Use cheap stretch mesh (20 denier) or an old t-shirt jersey. You must test the stretch ratio.
